This invention relates to manure spreaders and has particular relationto .that part of the spreader which distributes the manure over a path other than the vehicle body and which part is called the wide-spread.

-It has been customary to construct the wide-spread with; blades equally spaced alongits shaft and equally'spaced around its shaftL i r j a In developing this invention it was determined that due to the shape of the "load with more manure near the centerof the vehicle that as the manure-is fed to the rear, an even spread wasnot exactly obtained with this equal arrangementof the blades.

the provision ofan improved manure spreader wide-spread whichwill distribute --the manure evenly over the ground.

' Another object of this invention is the radially unequally spaced about its axis,

provisionof awide-spread having a shaft,

unequallyspaced about the axis with more blades to take care of the load adjacent the center line of its travel. q 7 I Another and further object, of thislinvention is the provision of a wide-spread which mounted thereon so that the' whole is balanced, yet the blades are unequally spaced about the axis in a manner that more blades are availablelto spread the load adjacent the center than the ends. a j

Another and still further object of' this invention is the provision of ,a wide spread blade having an. improved disintegrating effect-whereby the manure isbroken up into fine particles; 1

The primary object of this invention is provision of a wide-spread which has blades the whole being balanced andhaving blades spread detached, slightly enlargedand showing the relative arrangement of the parts.

Figures 3 and 4 are sectional views on lines 3-3and 1 -4, respectively of Figure 2,

- but for clearness omitting the showing of some of the blades. 1

The numeral 10 designates the rear end of the body of the vehicle of the manure spreader, 11 the discharging element which may be of any suitable design to removethe manure i'romthe rear of the load which is slowly moved to the'rear by suitablemecha- The discharger 11 is mounted: on a suitable shaft 12 whichcarries a suitable sprocket, -13 which is dr'ven by a suitable sprocket chainl i.

The shaft 12 also carries a suitable sprocket drive the latter. The wide-spread shaft is Anotherobject of this invention is the mounted in suitable hangers 19 which are supported" by the frame'membe'rs 20.

The wide-spread shaft 18 carries the widespread blades which will now be described.

As usually loaded, a manure spreader is loadedmore heavily along the center line of the vehicle, it being the natural tendency to load the vehicle with as heavy a load as possible. Sincethe load moves bodily along the sides and bottom of the vehicle, there is presented at the discharger element, more material adjacent the center; In this. in-

vention, provision has been made for'taking care of this greater amount of material. v

In thefembodiment herein described, there are illustrated" eight blades. These blades are so arranged that while perfectly balanced. 7

there are more blades presented to the load 7 V U adjacent the middle than adjacent the ends Other and further objects ofthis inven-Y the wlde'spread shaftl n q al 1- tion will be apparent from a reading of the 30 posit on of the blades, and'also'as to;the 1 'eof the shaft' and 22. These blades are in the embodiment herein shown and described, arranged120 in advance of the blades 21 and 21, respectively, in the. direction ofrotation.

.Outwardly of the'blades 22 and 22 respectively and toward the ends of the shaft 18 are the blades 23 and 23. These blades 23 and 23 arearranged respectively 120 behind the blades 21 and 21 and 120 inadvance of the blades 2 2jand 22 relative to the direction of rotation ofthe shaft 18.

outwardly of the blades 23, 23 are the blades 24, 2d, respectively. Itwill be noted. that the blade 24 is arranged at 180 from j the blade 24t- -on theopposite 'side'of theshaft 18 and that the blade 24 occupies a sin'iilar po,sition relative to the blade 23"..

The whole unit is'balancedboth'as to the action to the manure. out, the blades v 21 ,and 21; are arranged at 180 from each other on opposite sides'of the shaft. The same relation exists as to position with the pairsof blades 22, 22 23, 23 and. w en.

Each blade throws the manure contacting therewithto its own side, thus making four blades thr owing manure to oneside andfourthrowing manure to the opposite side. This.

brings. about a balance in thrusts along the axis of the shaft. I a I I g j Theblades 21 and 21 are, in-the illustrated embodiment, slightly closer together than any other two adjacent blades,

It is thus seenthat the group of blades 21,.

i 21* adjacent the middle of the shaft are closer together axially than any other two blades.

The groups 21, 22, 23 and 21, 22, 23 are arranged at 120 apart about the shaft 18 and the groups 23, 24: and 23*,2 l are at 180 apart. As the shaftrevolves all of the blades as annit, it is clear that more material fronr the discharger 11 will be taken care of at andadjacent themiddle ofv the shaft 18 than adj acent the ends. By this means an equal. distribution of the load over the field is effected.

In order to provide a convenient arrangement to hold the blades in proper position, I use a hexagonal stock for the construction of the shaft 18. To secure the body of. the blades 21, 21 22, 22 23, 23 24, 24 to the shaft 18, Iprovide suitable holders of two types.one for the right side of the shaft and one for the left. Each holder has a hexagonal opening to receive the shaft 18 and a blade attaching arm to which the blade is suitably bolted or riveted. The holders on the right of the machine as shown in Figure 2, I have designated by thenumeral 25 and those on the opposite side-of the middle, I have illustrated by the character 25 The holders .25 and 25 are suitably bolted or rivetedlin' place on the shaft.

The holders are so constructed that they will hold the blade bodies at about 45 to the plane normal to the shaft axis.

, It has been found-that the lumps of manure are broken up not only at the impact with the faces of the blades, but experiments have shown that by increasing the edge length suflicientl'y, the breaking up of the manure may amount to a pulve'rization. With the construction as illustrated, the largest par- ,ticles of'manure, asspread, are about. half the size as, when the edge'length is not in- 1 creased. As a practical solution of the problem, since the greater portion of thei particles of manure-leave the'blade from the outer third ofithe blade, there is illustrated, an indentation 26,, extending from the outer periphery towardthe axis for about one third the depth. The exact shape and size of the indentation is relatively unimportant. In

the structureshown, with the blade as'illus- As already pointed trated', a single'indentation is illustrated. The number of indentationsper blade may be increasedand in case a'blade had a greater angulaiywidth, the number. of indentations might well be multiplied; j

It is believed that the above description,

taken with the showing on the drawing shows clearly that this invention produces an even distribution of the. manureand a great pull. verization of the same as it leaves the blades for delivery to the] ground.

In some of the claims, I use the word ra diallyf This refers to the axis of the blade which extends from the shaft axis outwardly.

' While there is; shown and described in detailan embodiment of this invention, it is desired to have it understood that modifications andchanges may be made without departing from thespirit of the invention and within the scope of the appende laims.
